Another interesting Chiffchaff. This one was at Broom GP. I initially saw two birds in the willows - one dingy grey collybita type which was calling constantly, and then this bird. I hadn't noticed it until I tried playing tristis song at the collybita bird (just to see if it would react more than anything else), and this bird popped out from the bottom of some willows and started flapping its wings and bouncing around the branches above me. Unfortunately this bird remained silent throughout.

Plumage wise this is an odd bird. From a distance it looks buffy and brown, with the only real green around the wings and tail. Up close the green is much more evident, especially around the mantle, flanks and in the supercillium. The two chiffchaffs in this clump also act differently - the collybita is often much higher up in the top third of the willows, but this bird is usually at the very bottom - usually in the bottom two feet, just above the water.

To say that chiffchaffs do my head in is an understatement! As others have said, its redpolls all over again...

On Monday I had a cracking afternoons gulling in Cambs. I started off at the tip at Milton and spent two happy hours pouring through the few thousand gulls coming and going. Top of the pops were up to six Caspian Gulls, with a back up of around ten Yellow-legged Gulls. I was disappointed not to bag myself a white-winger as up to two juv Glaucs had been seen the previous few days. At around 3:15 I thought I should give the Grafham roost a go. I was pushing it get there before it got too dark, but managed to pull up just after 4pm

I started scanning from the fishing lodge and within five minutes I had found a lovely looking adult Glauc not far off shore. All other hopes of finding more Caspo's drifted in to the darkness as I happily watched my first adult Glauc of a good few years.

The videos above were digiscoped (at great distance!) with a Swarovski ATS 80 HD, 25-50x zoom, and Nikon V1 and kit lens.

At the same time I found the 'other' Siberian Chiffchaff at Marston Sewage Works I also came across this bird. It is distinctly different - its more beige and buff in colouration, without the greyness of the other bird. The wings and tail, although tinged green, aren't nearly as bright as the other bird, and it also has a light wingbar. This bird is also much more confiding and spends more time in low vegetation. It has also been silent on every visit - or at least I haven't seen it call, or been close enough when it has.

On close inspection there is some yellow in its plumage - however this is only visible in the images above. None of this yellow was visible in the field.

Looks ok for tristis, doesn't it. Its a nice shade of grey-brown, with green restricted to the wings and tail. That's all well and good, but now listen to it...

It's not the 'classic' tristis peep. It sounds a lot more like a collybita. I wonder, what do grey abietinus sound like? Do they exist? And if they do exist, would they look and sound like this?

There is currently an interesting discussion on the Surfbirds forum of a similar bird from Sweden. The video shows a grey tristis type chiffchaff calling like a collybita. The thread can be found here.

What is"bird porn"?

Well, I reckon its just nice image of birds. Really nice images of birds. In fact, it doesn't really have to be birds if you look down my blog. I started at birds, but it's widened to mammals too. So, really nice images of birds AND mammals then. There, sorted.
